WINDOW-SCREEN FIXTURE.

SPECIFICATION forming part of Letters Patent No. 391,106, dated October16, 1888.

Application filed June 28, 1888. Serial No. 278,493.

To aZZ 2072 0712 it may concern.-

Be it known that I, EDMUND H. AMBLER, of Beatrice, in the county of Gageand State of Nebraska, have invented a new and useful Improvement in\Vind'ow-Sereen Fixtures, of which the following is a specification.

The object of my invention is to provide a set of fixtures to adapt anywindow to receive a screen of the usual construction, which screen shallnot interfere with the raising and lowering of thesash, but may beconveniently taken out and replaced for opening and closing the outsideblinds.

It consists in a set of disconnected and rabbeted bushing strips adaptedto tit in the grooves in which the sashes slide, and pr0- vided withfastenings for securingthe screen therein, as will be hereinafter fullydescribed.

Figure 1 is a front view of the inside of the window-frame provided withmy improvement. Fig. 2 is a horizontal section through line a; m; Fig.3, a vertical section through line 3 y; and Fig. 4, a perspective viewof the bushing-strips on a reduced scale, and showing the said strips inposition to be assembled to form a supplementary frame.

A is the window-frame, and B B its two sashes,which slide, as usual, inthe two grooves a a in the sides of the frame.

0 is the screen, which may also be made of the usual construction, as anordinary rectangular frame, provided with a netting of gauze-wire.

D D and E E are four bushing-strips, which, together, form asectionalsupplementary frame that receives and holds the screen and is seated inthe grooves of the frame at the end of one of the window-sashes. Thesebushing-strips are made of a thickness corresponding to that of thesash, so that they fit in the grooves in which the sashes slide. Thesestrips are each provided with a projecting flange, d d and e e, on theirouter edges, formed by rabbeting the strips, which flanges on the topand bottom strips run the full length of the strips, and on the sidestrips are shorter by the width of the flange on the top and bottomstrips, upon which they rest. The top strip, D, is provided with lips orcleats b on its inner face, which overlap the edges of this strip andform locking-lugs, behind which the top edge of the screen is seated andsecured, and the bottom strip, D, is provided with a button or catch, a,which may be turned to lock the lower edge of the (No model.)

screen after it is seated in the rabbct of the strips.

In adapting my invention to the windowframe the horizontalbushing-strips are adapted in length to the width of the window frame-i.0., from the inside of one groove to the inside of the other-and theside strips are made of a length to completely fill the space in theside grooves below the upper sash, abutting at the top against the upperhorizontal strip, D, and at the bottom against the lower horizontalstrip, D, the side strips, E E, and ends of horizontal strips D D beingso grooved as to admit of said cord or chain working withoutinterference when frame and screen are applied to upper part ofwindow-frame. Thestrips thushold themselves in place and form a seatinside the flange, which permits the screen to be placed laterallytherein, and secured by the lips or cleats b at the top and the buttonor catch 0 at the bottom, the screen and strips resting in the plane ofthe sash, so as to permit the other sash to be raised or lowered withoutinterfering with its movement.

This screen may readily be taken out and replaced without any change orreadjustment of the bushing-strips, and the latter with the screen maybe placed in the groove below the upper sash or in the groove above thelower sash, as may be desired.

I am aware that a window-screen has been set in a rigid supplementaryframe, as shown in Patent No. 268,101, and I do not claim thisconstruction.

Having thus described my invention, what I claim as new is Thecombination, with a window-screen, of a set of four disconnectedrabbeted bushingstrips, D D E E, made each of the width of thesash-groove, the strips D D being arranged horizontally and having theiropposite ends seated in the sash-grooveson the opposite sides, and thestrips E E being arranged vertically and having their sides seated inthe sash-grooves and their ends abutting against the horizontal strips,and fastenings, substantially as described, for holding the screen inthe rabbct of the strips, as and for the purpose set forth.

EDMUND H. AMBLER.
